VOREL INTERNAL COMBUSTION ENGINE Filedeb. 21,. 192,8 `s sheets-sheet 3 r'nmvx vaREL plied to an internal combustion` engine of the four cycletype and having four alined cylinders, though it may be used in construction having more or fewer cylinders, or in engines of the two cycle type, as will later be made evident. The general arrangement of the Y casing 6 relative to the several cylinders is Y somewhat conventional, that is 'to'say, said` casinghas opposi'tely directed apertures 10.

and l1 for use in conjunction withthe inlet aperture 12 of each cylinder, usually theupper one 10 connecting with'theintakemanitending in either direction from tliedisc, thus fold. and the lower 11 serving for the eX- haust opening. The-valve shaft serves for" suitable registration of these openingsl and 11,respectively, with the cylinder aperture 12, as usual. Y

My valve shaft 5 is madeup of a number.

fof detachable sections 13, each of which comprises a cylindrical discv 1 4 mounted Afivedly upon areduced axial stem or shaft 151er(- `providing extensions for rotating the valve of the disc-s. y Y

uagainstrotation ordinarily by a'` peripheral .,discs, as stated. The sections V13 are rotated together inunison by the provision onthe `ends of lthejextensions, yof keys or tongues 16 and slots 17, the tongue of one extension engaging theV slot of theneXt, as shown.

Mounted within the .casing andVV between the'discs 14 ofadjacent sections 13, I provide .bearing cylinders 18lwhi'ch are apertured axially to receive therein'the extensions These cylinders 18 vare held notch orslot k19 to beengaged'bya key'20 in the casing surface. While it'may be possible to provide but one such cylinder18 between adjacent discs 14, I have found it feasible 'and advantageous to form such bearing meinbers in two parts2l oppositely directed, for` reasons hereinafter explained.

' Vhile rotary valvesffor gasengines have been used before, and such 'construction has been used comprising detachable sections rotating in unison, the sections have been made up of discsv whose internalY channels haveV registered directly with the intakeand exhaust apertures in the casing and thereby with 'the respective manifolds.v TheV bear ing membersorl'sleeves have'then 'usually been solid, exceititV whensmalll longitudinal 'openings or channels have" been provided through them for lubrication. This old con-Y 'struction requires therefore," as many 'valve l discs as valveg Y'there arel cylinders, in thi'sjtype of attention 'is @aina afaiatimaamytwa Y Vprior Patent No.. 1,6` 47,5' 92,'; "Novemberr 1,

Each 'of these channels are positioned on a common radius and open at vtheirends at the' opposite faces of the disc at circular openingsg24 positioned .positively radiallyl from the periphery of the'disc, and

consequently spaced from the inner: wall of Vthe casing 6.',v

To suitably coordinate these openings 24 witlitlie corresponding apertures 12 leading to thevseveral'cylinders 7 the cylinders or asleeves'lS are provided with three channels 25, 26 and v27, as shwnginFigs. 9 andlO,

Awhich lead to theapertures 1 0, 1l and 12,

As in theusual andV more commonzconstruction, the end stems 15 of theend sections vof the valve are mounted for rotation in end plates28 of the casing, the one' end of the valve stem having an external sprocket 29 alining with sprocket 30 on 'the shaft 9,"and the two sprockets geared to drive the rotary valve 5 at proper In the relative speed tothat'pof the shaft 9, by the chain3`2.V 1
